title: A successful patch angioplasty with auto-pulmonary wall for congenital coronary left main trunk occlusion in a young child.
abstract: Congenital occlusion of the left main coronary trunk is a life-threatening abnormality, and its optimal management remains controversial. This report describes a case of successful patch angioplasty with auto-pulmonary artery for a 12-year-old boy with congenital left main trunk occlusion. We divided the main pulmonary artery, harvested a pulmonary artery wall strip, and performed patch angioplasty of the occluded left main trunk ostium. We were able to clearly expose the left main trunk behind the pulmonary artery because the obstruction was divided for the patch material. The postoperative course was uneventful, and coronary angiography at 4 months after surgery showed excellent patency of the left main trunk. The auto-pulmonary arterial wall was easy to handle during angioplasty, and its favorable durability has been established both in the Ross procedures and in an arterial switch procedure. Therefore, we conclude that patch angioplasty using a piece of the pulmonary arterial wall represents a good alternative to conventional coronary artery bypass grafting.
